A multi-camera vision system for a vehicle includes first, second and third image capture devices having respective first, second and third fields of view exterior of the vehicle. The first field of view overlaps with the third field of view defining a first overlap zone, and the second field of view overlaps with the third field of view defining a second overlap zone. Responsive to processing of captured image data, a synthesized image is generated without duplication of objects present in the first and second overlap zones and the synthesized image approximates a view as would be seen by a virtual camera at a single location exterior of the vehicle. The synthesized image is displayed by a single display screen that is viewable by a driver of the vehicle and the synthesized image assists the driver in executing a maneuver of the vehicle with a trailer attached thereto.

A driver assistance system for a vehicle includes an imager disposed in a housing and a control. The imager includes a CMOS photosensor array of photosensor elements and a lens. With the housing disposed in a vehicle, the imager views forwardly to the exterior of the vehicle through the vehicle windshield at a region of the windshield that is swept by a windshield wiper of the vehicle. The CMOS photosensor array is operable to capture image data. The control includes an image processor disposed in the housing. The driver assistance system identifies objects viewed by the imager via processing by the image processor of captured image data. At least in part responsive to processing of captured image data by the image processor, streetlights present exterior of the vehicle and viewed by imager are discriminated from other objects present exterior the vehicle and viewed by imager.

A multi-camera vision system for a vehicle includes first, second and third image capture devices disposed at respective vehicle portions. The first image capture device field of view overlaps with the third image capture device field of view defining a first overlap zone, and the second image capture device field of view overlaps with the third image capture device field of view defining a second overlap zone. Responsive to processing by an image processor of received image data, a synthesized image is generated without duplication of objects present in the first overlap zone and in the second overlap zone. The synthesized image approximates a view as would be seen by a virtual camera at a single location exterior of the vehicle, and is displayed by a single display screen of a reconfigurable display device that is viewable by a driver of the vehicle when normally operating the vehicle.

A driver assistance system for a vehicle includes an imager and a control having an image processor. The imager is disposed at or proximate to an in-cabin portion of a windshield of a vehicle and has a forward field of view to the exterior of the vehicle through the vehicle windshield. The driver assistance system identifies objects in the forward field of view of the imager via processing of captured image data by the image processor. At least in part responsive to processing of captured image data by the image processor, a determination is made that the vehicle is being operated in an urban environment. Responsive to the determination that the vehicle is being operated in an urban environment, operation of a driver assistance function of the vehicle is inhibited.
